The purpose of this study was to determine the lifetime risk
of revision surgery for patients undergoing Charnley cemented total
hip arthroplasty (THA), with 40-year follow up, using death as a
competing risk. We retrospectively reviewed 2000 cemented Charnley THAs, with
51 living hips available at 40 years. Aims

Promising medium-term results from total shoulder arthroplasty
(TSA) have been reported for the treatment of primary osteoarthritis
in young and middle-aged patients. The aim of this study was to
evaluate the long-term functional and radiological outcome of TSA
in the middle-aged patient. The data of all patients from the previous medium-term study
were available. At a mean follow-up of 13 years (8 to 17), we reviewed
21 patients (12 men, nine women, 21 shoulders) with a mean age of
55 years (37 to 60). The Constant-Murley score (CS) with its subgroups
and subjective satisfaction were measured. Radiological signs of implant
loosening were analysed.Aims
Patients and Methods
Restoring the pre-morbid anatomy of the proximal humerus is a
goal of anatomical shoulder arthroplasty, but reliance is placed
on the surgeon’s experience and on anatomical estimations. The purpose
of this study was to present a novel method, ‘Statistical Shape
Modelling’, which accurately predicts the pre-morbid proximal humeral anatomy
and calculates the 3D geometric parameters needed to restore normal
anatomy in patients with severe degenerative osteoarthritis or a
fracture of the proximal humerus. From a database of 57 humeral CT scans 3D humeral reconstructions
were manually created. The reconstructions were used to construct
a statistical shape model (SSM), which was then tested on a second
set of 52 scans. For each humerus in the second set, 3D reconstructions
of four diaphyseal segments of varying lengths were created. These
reconstructions were chosen to mimic severe osteoarthritis, a fracture
of the surgical neck of the humerus and a proximal humeral fracture
with diaphyseal extension. The SSM was then applied to the diaphyseal
segments to see how well it predicted proximal morphology, using
the actual proximal humeral morphology for comparison.Aims

Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors need to be identified. The objective of this study was to identify the pre-operative prognostic factors related to the effect of vertebroplasty on acute pain control using a cohort of surgically and non-surgically managed patients. Patients with single-level acute osteoporotic vertebral compression fracture at thoracolumbar junction (T10 to L2) were followed. If the patients were not satisfied with acute pain reduction after a three-week conservative treatment, vertebroplasty was recommended. Pain assessment was carried out at the time of diagnosis, as well as three, four, six, and 12 weeks after the diagnosis. The effect of vertebroplasty, compared with conservative treatment, on back pain (visual analogue score, VAS) was analysed with the use of analysis-of-covariance models that adjusted for pre-operative VAS scores.Objectives

Since redesign of the Oxford phase III mobile-bearing unicompartmental
knee arthroplasty (UKA) femoral component to a twin-peg design,
there has not been a direct comparison to total knee arthroplasty
(TKA). Thus, we explored differences between the two cohorts. A total of 168 patients (201 knees) underwent medial UKA with
the Oxford Partial Knee Twin-Peg. These patients were compared with
a randomly selected group of 177 patients (189 knees) with primary
Vanguard TKA. Patient demographics, Knee Society (KS) scores and
range of movement (ROM) were compared between the two cohorts. Additionally,
revision, re-operation and manipulation under anaesthesia rates
were analysed.Aims

We have previously investigated an association between the genome copy number variation (CNV) and acetabular dysplasia (AD). Hip osteoarthritis is associated with a genetic polymorphism in the aspartic acid repeat in the N-terminal region of the asporin ( Acetabular coverage of all subjects was evaluated using radiological findings (Sharp angle, centre-edge (CE) angle, acetabular roof obliquity (ARO) angle, and minimum joint space width). Genomic DNA was extracted from peripheral blood leukocytes. Agilent’s region-targeted high-density oligonucleotide tiling microarray was used to analyse 64 female AD patients and 32 female control subjects. All statistical analyses were performed using EZR software (Fisher’s exact probability test, Pearson’s correlation test, and Student’s Objectives

The purpose of this study was to compare the results and complications of tibial lengthening over an intramedullary nail with treatment using the traditional Ilizarov method. In this matched case study, 16 adult patients underwent 19 tibial lengthening over nails (LON) procedures. For the matched case group, 17 patients who underwent 19 Ilizarov tibial lengthenings were retrospectively matched to the LON group.Objectives

Our aim in this study was to describe the long-term survival
of the native hip joint after open reduction and internal fixation
of a displaced fracture of the acetabulum. We also present long-term
clinical outcomes and risk factors associated with a poor outcome. A total of 285 patients underwent surgery for a displaced acetabular
fracture between 1993 and 2005. For the survival analysis 253 were
included, there were 197 men and 56 women with a mean age of 42
years (12 to 78). The mean follow-up of 11 years (1 to 20) was identified
from our pelvic fracture registry. There were 99 elementary and 154
associated fracture types. For the long-term clinical follow-up,
192 patients with complete data were included. Their mean age was
40 years (13 to 78) with a mean follow-up of 12 years (5 to 20).
Injury to the femoral head and acetabular impaction were assessed
with CT scans and patients with an ipsilateral fracture of the femoral
head were excluded.Aims
Patients and Methods
Patients undergoing femoral lengthening by external fixation
tolerate treatment less well when compared to tibial lengthening.
Lengthening of the femur with an intramedullary device may have
advantages. We reviewed all cases of simple femoral lengthening performed
at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities,
congenital limb deficiencies and lengthening with an unstable hip
were excluded, leaving 33 cases (in 22 patients; 11 patients had
bilateral procedures) for review. Healing index, implant tolerance
and complications were compared.Aims

The United States and Canada are in the midst
of an epidemic of the use, misuse and overdose of opioids, and deaths
related to overdose. This is the direct result of overstatement
of the benefits and understatement of the risks of using opioids
by advocates and pharmaceutical companies. Massive amounts of prescription
opioids entered the community and were often diverted and misused.
Most other parts of the world achieve comparable pain relief using
fewer opioids. The misconceptions about opioids that created this epidemic are
finding their way around the world. There is particular evidence
of the increased prescription of strong opioids in Europe. Opioids are addictive and dangerous. Evidence is mounting that
the best pain relief is obtained through resilience. Opioids are
often prescribed when treatments to increase resilience would be
more effective. Cite this article:
The widely used and well-proven Palacos R (a.k.a. Refobacin Palacos
R) bone cement is no longer commercially available and was superseded
by Refobacin bone cement R and Palacos R + G in 2005. However, the
performance of these newly introduced bone cements have not been
tested in a phased evidence-based manner, including roentgen stereophotogrammetric
analysis (RSA). In this blinded, randomised, clinical RSA study, the migration
of the Stanmore femoral component was compared between Refobacin
bone cement R and Palacos R + G in 62 consecutive total hip arthroplasties.
The primary outcome measure was femoral component migration measured
using RSA and secondary outcomes were Harris hip score (HHS), Hip
disability and Osteoarthritis Outcome Score (HOOS), EuroQol 5D (EQ-5D)
and Short Form 36 (SF-36).Aims

The aim of this systematic literature review was to assess the clinical level of evidence of commercially available demineralised bone matrix (DBM) products for their use in trauma and orthopaedic related surgery. A total of 17 DBM products were used as search terms in two available databases: Embase and PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement. All articles that reported the clinical use of a DBM-product in trauma and orthopaedic related surgery were included.Objectives

The August 2015 Shoulder &
Elbow Roundup360 looks at: Clavicular fractures are being fixed – but how?;
We describe the use of a protocol of irrigation and debridement
(I&
D) with retention of the implant for the treatment of periprosthetic
infection of a total elbow arthroplasty (TEA). This may be an attractive
alternative to staged re-implantation. Between 1990 and 2010, 23 consecutive patients were treated in
this way. Three were lost to follow-up leaving 20 patients (21 TEAs)
in the study. There were six men and 14 women. Their mean age was
58 years (23 to 76). The protocol involved: component unlinking,
irrigation and debridement (I&
D), and the introduction of antibiotic
laden cement beads; organism-specific intravenous antibiotics; repeat
I&
D and re-linkage of the implant if appropriate; long-term
oral antibiotic therapy. Aims

Hip resurfacing arthroplasty (HRA) is an alternative to conventional
total hip arthroplasty for patients with osteonecrosis (ON) of the
femoral head. Our aim was to report the long-term outcome of HRA,
which is not currently known. Long-term survivorship, clinical scores and radiographic results
for 82 patients (99 hips) treated with HRA for ON over a period
of 18 years were reviewed retrospectively. The mean age of the 67
men and 15 women at the time of surgery was 40.8 years (14 to 64).
Patients were resurfaced regardless of the size of the osteonecrotic
lesion.Aims
